The application works very badly, it does not synchronize with the IPhone, the thermometer is never detected by bluethoot and we cannot enter the data manually. Had I known, I would have bought only a basal thermometer without paying for an app that didn't work. ### 1/5 — Absolutely useless! *2020-10-21, version 1.3.7* It does not sync with iPhone or iPad and the thermometer does not work independent of the app. I cannot return the thermometer because it’s been “used”. So I’m out of pocket in this. Do not buy!!! ### 1/5 — Terrible terrible product *2020-10-09, version 1.3.7* Can’t get it to sync with the app. Thermometer won’t work in standalone mode - it just turns on and off and shows nothing else on the screen but “Set” - so it’s basically a small and completely useless brick. Avoid! ### 1/5 — Therm good, app bad *2020-10-07, version 1.3.7* Thermometer works fine but I have to use another app to chart my temps. I can’t get this one to connect to the thermometer at all, it only worked the first time for set up. Kind of defeats the purpose of buying this brand... could have got a cheaper non-bluetooth model since I cant use the bt on this one. ### 1/5 — Terrible app *2020-09-06, version 1.3.7* I would like to see a lot of progression in this app. I can’t add information, can’t see part of the calendar, the app doesn’t turn if I turn my phone, doesn’t pair with the thermometer for about the first three tries, there is no chart to actually follow a pattern in my cycle...etc. To be short and clear, this app is not done. ### 1/5 — Terrible. *2020-07-22, version 1.3.7* Very frustrating experience. The app sucks. While I was able to pair the thermometer to the phone, I was not able to do anything with it including setting the information in the profile, seeing the whole calendar, accessing the chart or settings. Will be returning. ### 1/5 — Not great *2020-06-19, version 1.3.7* The thermometer almost never pairs and only does so with great difficulty and multiple tries. The app is very basic and frequently doesn’t load. Would not recommend paying for this Bluetooth thermometer, you will likely not be able to use the Bluetooth function and have to input the temperature manually to a better app. ### 1/5 — Doesn’t work *2020-06-01, version 1.3.6* The app crashes whenever I try to create an account so I can’t use it or pair my device. ### 1/5 — Zéro *2020-04-21, version 1.3.4* L’application ne fonctionne même pas ! ### 1/5 — Du vol! *2020-03-24, version 1.3.4* Un gros zéro, de l’argent gaspillée pour un thermomètre dont je ne peux même pas me servir. L’application ne fonctionne pas même après des mois d’attente. ### 1/5 — Can’t register *2020-03-20, version 1.3.4* The app is on maintenance since weeks. So I can’t use my thermometer. ### 1/5 — Vraiment déçue *2020-03-20, version 1.3.4* L’application ne fonctionne pas, je ne peux même pas me créer un profil, donc mon thermomètre ne peut pas se connecter et ne fonctionne pas en conséquent! Très fâchée car dispendieux comme thermomètre! ### 1/5 — Impossible de créer un compte *2020-03-19, version 1.3.4* Un gros zéro !!! La raison pour laquelle j’ai choisi ce thermomètre c’est pour son application Bluetooth. Mis une étoile à cause que je suis obligé. ### 1/5 — Can’t register *2020-03-15, version 1.3.4* Like everyone else, I’m unable to register. Rendering the Bluetooth features of this device unusable. ### 1/5 — Cannot register *2020-03-09, version 1.3.3* Haven't been able to register since downloading this months ago. I've uninstalled and reinstalled, on both my iPhone and iPad, and nothing. If they're this incompetent with their app, I question how accurate the actual thermometer has been. "Trusted for over 3 generations" is clearly false and garbage. ### 1/5 — Un gros zero *2020-02-10, version 1.3.2* J'aurais même pas donner un étoile gros bugs incapable juste me crée un compte il as rien a faire! ### 1/5 — Ne fonctionne pas *2020-02-02, version 1.3.2* Incapable de seulement me connecter sur l’application..,. Gros zero ### 1/5 — Crashing *2019-10-27, version 1.3.1* App keeps crashing everytime I open it. It’s nice to be able to track my child’s fever and medicine within the app but if you can’t use it it’s pointless ## Most critical reviews (10 lowest-rated) ### 1/5 — Poor quality *2026-07-26, version 1.3.9* You can’t even register ### 1/5 — Useless *2026-02-05, version 1.3.9* Can’t even use it because the app just freezes while trying to register. ### 1/5 — Ne fonctionne pas *2025-12-17, version 1.3.9* Je ne suis pas capable de me créer un compte et le thermomètre flash une lumière verte depuis 10 minutes et ne veut pas ouvrir ### 1/5 — Doesn’t even deserve 1 star. *2025-03-27, version 1.3.9* This app doesn’t even let you create a profile. GARBAGE ### 1/5 — Waste of time and miney *2024-10-21, version 1.3.9* The app won’t even let you register, it just freezes. The thermometer is just as crappy. Wouldn’t turn on properly and we couldn’t make it work. ### 1/5 — Don’t ever buy a BIOS ovulation thermometer *2023-01-14, version 1.3.9* Even one star review is too much. It is completely unusable. I bought a BIOS ovulation thermometer but I couldn’t even do the configuration ! The app is so poorly designed that it is not even possible to go in the setting tab which is a mandatory step to do the configuration. There is so much flaws that I can’t list them all here. BIOS should hire a UX designer for users’ sake. ### 1/5 — App is poorly fabricated *2022-09-15, version 1.3.9* There are a lot of issues with the app’s usability. Many functions do not work (e.g. I could not select tips or settings), I also had an issue with inputting a date for my profile as the month and year would not show, and my temp reading for the day would not show nor could I input it. ### 1/5 — Does not work *2021-07-19, version 1.3.9* Thermometer not accurate and does NOT sync with app. App is also completely glitchy and basic. Overall a 0 stars. Don’t waste your money on this. ### 1/5 — Useless- doesn’t connect *2021-05-27, version 1.3.8* This is the worst app ever. It doesn’t pair with the thermometer after hours of trying to get it to and trouble shooting every possible option. If you haven’t already used the thermometer I recommend returning it and getting a different one- So frustrating!! ### 1/5 — DOESNT CONNECT *2021-02-23, version 1.3.8* Bad product. Lost my money on this promising looking product. There are Connection issues. Sometimes it works after I pester it for a solid 30 min. I don’t have that kind of time or patience for that every morning. Don’t buy. ## Most praised reviews (3 highest-rated) ### 4/5 — Thermometer and App are great *2020-06-02, version 1.3.6* I have been using the app and thermometer for some time. Once I got the thermometer sync’d with the app, the thermometer is easy to use. I don’t update my temp everyday to the app as I know there is memory in the thermometer, but when I do the app and the thermometer pair and the readings come through. Glad they got it back up and running as it was down for updates. The app is basic, but it doesn’t need to do a lot and I’m ok with that. ### 3/5 — Non-fonctionnel pour l’instant *2019-10-07, version 1.3.1* L’application se ferme dès l’ouverture depuis la mie à jour de mon Iphone! ### 2/5 — Doesn’t easily sync *2020-06-14, version 1.3.7* I bought this thermometer because I can track temperatures with the app but syncing doesn’t always work. It would also be nice to easily view temperatures on a chart or in a list. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
